Doctor Impossible is a fictional supervillain created by DC Comics. He first appeared in the comic book Justice League of America, vol. 2 #1. Brad Meltzer and Ed Benes created this character, who was inspired by the concepts of Jack Kirby.
Prior to his actual appearance, rumor went spread amongst the criminal underground that he was a thug who previously worked for the Penguin. It is said that his name is Jonas Lock and that at some point he acquired his technology from Apokolips. Dr. Impossible himself claims to be the brother of Mr. Miracle and to have come from Apokolips. Impossible looks like a dark doppelganger of Mr. Miracle, and has equipment/skills to match.
After he arrived Earth, Impossible was controlled by Professor Ivo, Electrocutioner, Plastique, and Karate Kid (in the guise of Trident), and Solomon Grundy through a mechanically enhanced Starro parasite. The brainwashed villains were used to gather raw materials for the construction of a robotic body to hold the mind of Grundy. Doctor Impossible stole the body of Red Tornado and the arm of the Parasite, but was defeated by members of the Justice League.
Doctor Impossible returned, accompanied by evil duplicates of several New Gods, to seize an alien machine that is buried on Earth for centuries. His new associates are Neon Black, Hunter, Chair, and Tender Mercy, duplicates of Lightray, Orion, Metron, and Big Barda, respectively. Impossible and his team are powerful enough to defeat Josiah Power and his team, the Power Company, in combat. They are later seen breaking into the Justice League Watchtower to steal alien artifacts. After successfully stealing the artifact, the villains are ambushed by the newly arrived Green Arrow, who is on the run after killing Prometheus. Impossible and his partners are eventually forced to flee after a damaged Red Tornado uses his headless body to attack them. Impossible combines the stolen artifacts and creates an advanced machine. He places the kidnapped Justice League Europe member Blue Jay inside of it. This opens up a gateway to the Multiverse, which Impossible claims to do at the behest of an unnamed client.
Afterward, Doctor Impossible determines that the Crime Syndicate of America (CSA) is planning to resurrect Alexander Luthor, Jr. in the chamber of resurrection. Impossible and the CSA arrive on New Earth to attack the Justice League of America (JLA) in the Hall of Justice, their headquarters. While the other CSA members keep the JLA busy, the supervillain Owl Man sneaks off to allow Dr. Impossible access to the resurrection device. At the last moment, Doctor Impossible double-crosses the CSA and has Hunter remove Alexander Luthor's corpse and substitute himself in order to resurrect Darkseid. The resurrection machine destroys Rip Hunter, who shrieks in agony. A character appears within the smoke of the containment device, Doctor Impossible exults to his team that Darkseid has returned. The being before them is not Darkseid, however, but the Omega Man, who blasts Black Neon and Tender Mercy, killing them. As Doctor Impossible plan failed and flees from Omega Man attacks.[clarification needed]
